What do R and P most likely represent?

A.) R represents chemical energy, P represents thermal energy

B.) R represents thermal energy, P represents chemical energy

C.) R represents potential energy, K represents electrical energy

D.) R represents electrical energy, K represents potential energy

Answer is: A.) R represents chemical energy, P represents thermal energy.

A natural gas stove transforms R energy into P energy.

For example methane is natural gas.

Balanced chemical reaction of methane combustion:

CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (g) ΔH = - 802.3 kJ.

This is exothermic reaction, energy is released in form of heat.

The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another.
